Math Problem Statement
The Heaviside function H is defined by
H(t) =
0
if t < 0
1
if t ≥ 0.
Solution
The Heaviside function, often denoted by , is a step function that is widely used in control theory, signal processing, and differential equations. It is defined as follows:
\begin{cases} 0 & \text{if } t < 0, \\ 1 & \text{if } t \geq 0. \end{cases}$$ ### Explanation: - **For $$t < 0$$:** The function outputs 0. This represents the "off" state or zero value before a certain point in time. - **For $$t \geq 0$$:** The function outputs 1. This represents the "on" state or unit value from the point $$t = 0$$ onwards. ### Translation in Terms of Heaviside Function: If you wanted to translate the Heaviside function, for example, to start the "step" at $$t = a$$ instead of $$t = 0$$, you would write: $$H(t - a) = \begin{cases} 0 & \text{if } t < a, \\ 1 & \text{if } t \geq a. \end{cases}$$ This formula shifts the step to occur at $$t = a$$.
